For events specifically, my cohort (somewhere between Gen-Z and Millenial) have moved event organizing entirely to Partiful, which I've found to be far superior to Facebook Events. Doesn't help with group posts though.
Their use of good old fashioned www links and SMS messages makes it easy for everyone to share and join events. No app and no Partiful account necessary.
They also have simple and good event privacy model, group scheduling, reminders, Venmo based ticket system, and group chat.
It’s taken over almost completely in my social circles and I’m all for it.
It seems like they might have group organizing features now, but I'd be concerned about adopting it for a group without a clear idea of how they're going to make money
> Partiful does not make money yet. They are a venture-backed startup with many millions of dollars of funding. They will eventually offer a premium version, an ad-supported model, or be acquired by a larger company like Eventbrite, Ticketmaster, Snapchat, or one of these other potential acquirers.
Basically, enjoy it while you can. There is nothing wrong with using a free service like this while you can. Best case IMO is that they monetize it with low fees and have a product that is actually worth paying for.
